UNITED STATES PATENT OFF C PHlLlP KLOTZ, OF BALTIMORE, MARYLAND, ASSIGNOR TO BENTLEY C. BIBB, OF SAME PLACE.

RANGE.

SPECIFICATION forming part of Letters Patent No. 364,116. dated May 31, 1887.

Application filed May 2i, 1886. Serial No. 202.907. (No model.)

'zen of the United States, residing in the city of Baltimore, State of Maryland, have invented certain new and useful Improvements -in Ranges, of which the following is a specia transverse sectional elevation of a range placed in position and illustrating my improvement. Fig. 2 is'a front elevation, partly in section; Fig. 3, a plan, the brick-work in section; Fig. 4, a sectional elevation showing a modification.

Heretofore it has been common to arrange cooking-ranges so as to form at the rear thereof,

between the back plate of the oven and the wall a, a chamber which is supplied with air, and from which a conducting-pipe extends to a room above, so that the airheated by contact with the back plate of the stove may serve as a means of heating the upper room. While this arrangement is effective in securing a certain amount of heated air for the upper apartment, the air is not very highly heated, and the chilling of the back plate of the oven is most detrimental to the efficiency of the range.

To overcome these objections, I providethe range having the usual fire box or chamber separated from the oven by a partition,(shown by dotted lines, Fig. 2,) with an air-heating chamber,.y, at the back of thefirechamber orfire-box and ash-pit, and having no connection with the chamber at, and I admit the air to the said chamber 3/ and conduct it through a pipe, I), to the room or other place to be supplied with heated air without cont-act with or chilling any portion of the range which should remain in a heated condition.

Different arrangements may be employed for forming the chamber y at the rear of the fire-place and for ad mitting-air to and conveying it from the said chamber.

, In Figs. 1, 2, and 3 the chamber y is illustrated as contained within a casing, A, 'co'ver-.

ing the rear walls of the fire-chamber W and ash-pit V, and air is admitted to the lowerend of the said casing through a horizontal flue, B,

extending beneath the bottom of the ash-pitV,

through the chamber U, below the ash-pit, and adjacent to the warming-closet T, and air is admitted to the chamber I] through openings sin the side plate of the range. The rear wall of the chamber U is formed by a forwardlyprojecting deflector-plate, t, which serves to direct the inflowing air against the bottom of the ash-pit at the mouth of the flue B, so that the air in passing through the latter will be partially heated by contact with the ash-pit bottom before ascending into the chambery. The top plate,C, of the stove is provided above the chamber ywit-h an opening, 6, surrounded by a collar, f, to which the hot-air pipe bis applied, so that the pipe I) may be removed and a cap applied to the collar whenever it is dethe air, and to imparta higher temperature, I

construct the back plate, D, of the fire-box'so as to present a more extended surface to the air in the chamber 3 Thus the back plate may have projecting pins t, as shown in Fig 1, or it may be ribbed, or waved, the heatingsurface being thereby increased in area.

Where the top plate of the 'range does not project beyond the back plate of the stove, a separate plate may be employed to cover the chamberr, or the opening 6 may be put in communication with a flue formed in the brickwork.

In Figs. 1, 2, and 3 I have shown a construc tion which has proved to be effective in ranges 10o manufactured for the purpose of embodying my improvement; but the improvement may be embodied in ranges of ordinary construction by using a pipe at the back of the firechamber andash-pit to form the chamber 3 as shown in Fig. 4, and by inserting a false bottom, d, in the ash-pit, so as to form the flue B, an opening, 10, being made in the back wall of the ash-pit to form a communication between the flue and chamber 1 The cold air, instead of passing from the room in which the range is used, may be conducted to the flue B or to the openings 8 by means of an air-pipe, f, as shown in dotted lines, Fig. 2, or by an opening from the cellar,

' (dotted lines, Fig. 4,) or by a pipe comm unieating with the outside air.

Without limiting myself to the precise construction and arrangement of parts shown, I claim 1-. A cooking-stove having a fire-box extending to the back wall of the stove, an oven separated by its side wall from the fire-b0x,a chamber or space extending across the back of the stove from endto end, andan air-heating cham-.

ber, the back of the stove orfirebox constituting the front wall of said chamber, which is separated from said space, substantially as described.

3o 2. A cooking-stove provided with a firebox extending to the back wall thereof, an

oven at one side of said box, a cold-air inlet at the base, a space along the rear of the stove, and a flue extending from said inlet below the ash-pit to an air-chamber at the back of the stove independent of said space, substantially as described.

3. A cooking-stove provided with an airline extending under and parallel with the ashpit, and a vertical casing extending at the rear of the ash-pit and fire-chamber, substantially as described.

4. The combination, in a cooking stove, of the fire-box extending to the rear wall of the stove, ash-pit, side oven, horizontal flue extending beneath the ash'pit, space extending across therear of the stove, and vertical casing immediately in rear of the fire-box communicating with the horizontal flue and extending through the space at the rear of the stove without communicating therewith, sub stantially as described.

In testimony whereot'I have signed my name to this specification in the presence of two subscribing witnesses.
